HARRY E. REINISOH, OF NEW YORK, N. Y.

HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 620,497, dated February28, 1899.

Application filed March 30, 1898. Serial No. 675,703. (No model.)

To ttZZ whom it may concern:

Be it known that I, HARRY E. REINIscH, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in I-Iose-Oouplings,ofwhich the following is a full and complete specification, such as willenable those skilled in the art to which it appertains to make and usethe same. 1

This invention relates to hose-couplings; and it has for its object toprovide a sim ple and improved device of this character by which thehose can be more readily and conveniently detached from its pipeconnection.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by the same letters of reference ineach of the views, and in Which Figure lisa side view of the'improvedcoupling, and Fig. 2 is a longitudinal sectional View of the same.

Referring to the drawings, A designates a pipe which is preferably ofthe elbow form and which is provided adjacent to one end with an annularshoulder or portion a, and the end a thereof, adjacent to which saidshoulder or projection is formed, is screw-threaded. Mounted on thescrew-threaded end a of the pipe is a screw-threaded ring a provided inone side thereof with a perforation or opening a and I also provide apipe-coupling section E, with which the hose is adapted to be connectedand which, as shown in the draw ings, is provided at its inner end withan annular flange or rim 6. I

Between the annular flange e of the pipecoupling E and thescrew-threaded .end a of the tube A is placed an annular Washer orpacking-ring F, and the said pipe-coupling section E is provided with anannular cap B, having an inwardly-directed annular flange b at one end,which forms a circular opening through which the coupling-section Epasses and which operates in connection with the flange e on saidcoupling-section to hold said section in place and to press the sameagainst the annular washer or packing F.

The annular cap B is provided at one side with a hooked finger c, whichpasses through the perforation or opening a in the ring a and serves asa hinge, and said cap is provided at the opposite side with aspring-hook D, which catches overthe said ring a and holds said cap andthe coupling-section E in place and in the proper relative position withreference to the tube A. By means of this construction thecoupling-section E may be quickly and easily secured to the tube Awhenever desired and as readily and conveniently detached therefrom.

The hose may be secured to the section E in the usual or any desiredmanner, and the washer or packing F may be composed of any desiredmaterial, the object thereof being to provide a water-tight coupling.

This device is simple in construction and operation, and thecoupling-section E may be detached from the pipe A by simply pressingoutwardly on the end of the spring-catch d, when the annular cap B willswing to one side on the hooked finger c, which connects it with thering a Although I have shown and described the annular capB andcoupling-section as being formed separately, it will be apparent thatother forms of construction may be provided, and my invention is notlimited to the exact construction, combination, and arrangement of partsherein described; but I reserve the right to make all such alterationstherein as fairly come within the scope of the invention.

Having fully described my invention, I claimas new and desire to secureby Letters Patent- 1. In a pipe-coupling, the combination with a pipe,one end of which is screw-threaded and provided with a annular shoulderor projection, of a screw-threaded ring which is adapted to be screwedonto the screw-threaded end of said pipe, at l a coupling-sectionprovided with an ann' 7:1 cap having at one side a hooked finger whichpasses through said ring, and at the opposite side a spring-catch whichis adapted to engage with said ring, substantially as shown anddescribed.

2. Ina pipe-coupling, the combination with a pipe, one end of which isscrew-threaded and provided with an annular shoulder or projection, of ascrew-threaded ring which is adapted to be screwed onto thescrew-threaded end of said pipe, and a coupling-section pro vided withan annular cap having at one side a hooked finger which passes, throughsaid ring, and at the opposite side a spring-catch which is adapted toengage with said ring, said coupling-section and said cap being providedwith interlocking flanges, substantially as shown and described.

3. In a pipe-coupling, the combination with a pipe, one end of which isscrew-threaded and provided with an annular shoulder or projection, of ascrew-threaded ring which is adapted to be screwed onto thescrew-threaded end of said pipe, and a coupling-section proring, and atthe opposite side a spring-catch which is adapted to engage with saidring, said c0up1ing-section and said cap being provided-withinterlocking flanges, and a packing-ring placed between thecoupling-section and the screw-threaded end of said pipe, substantiallyas shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 28th day of March,1898.

HARRY E. REINISOII.
